BJA Magnetics
BJA Magnetics is a Leominster, Massachusetts-based manufacturer and supplier of engineered permanent magnet products and assemblies with over 35 years of industry experience, holding the rare triple certification of AS9100D, ISO 9001:2015, and ISO 13485:2016 — making it one of a relatively small number of magnet companies simultaneously qualified for aerospace, defense, and medical device supply chains. The company’s product portfolio spans permanent magnets across all major material families, proprietary Micro-Magnets™ designed for precision medical, wearable, sensor, and watchmaking applications, and custom magnetic assemblies for robotics, automation, aerospace EVTOL, and warehouse logistics — supported by in-house magnetizing and recycling services, magnetic testing with Helmholtz coils and M-Axis flux analysis, 3D printing in high-temperature and flame-retardant materials, laser engraving, and design assistance including magnetic modeling and holding force calculations. BJA also operates as a 100% women-owned business, and has earned customer recognition from Google, Apple, Microsoft, Philips, Swatch, and Johnson & Johnson for consistent quality and on-time delivery performance.
